Tools for stone carving. For Stone Artwork Diamond Stone Cutting Tool
Most natural stones have a shapeless and massive rock, so they need to be processed. One of the easiest and most common ways to work with stones is to cut them. There are several ways to perform this process, which we will discuss next.
In the mechanized type of stone industry, there are many technologies that allow the processing of stones and make their surface textured and attractive. We offer you to get acquainted with the most common methods of stone processing in industrial conditions:
1. Sawing - this method is carried out in the process of sawing a stone. For work, machines are used that have rectilinear discs on the saw frame. They are equipped with band and wire saws. After cutting, the surface acquires a slight roughness, and deep grooves do not exceed 5 mm. This stone will be an excellent material for paving sites, paths in the garden, facade decoration, etc. Also, these products are subjected to finer processing in the form of grinding or polishing.
2. Grinding - stone processing using a grinding wheel on machines specially designed for this purpose, which can grind volumetric workpieces. The stone becomes evenly rough, the irregularities on its surface have drops of 0.6 mm. This processing method is perfect for light-colored stones that do not have a pronounced pattern. If you apply it to a dark stone, then the pattern instantly disappears. A stone that has been polished will become an excellent material for finishing stairs, floors and street-type platforms. The stone significantly reduces slip, so it is boldly used in the decoration of these elements, as well as pools.
3. Achieving a polished texture of the product is carried out in the process of using a grinding wheel, which is coated with micro-grinding powder, usually diamond. The stone acquires a smooth, but not glossy surface. The texture of the product becomes more noticeable. This stone is perfect for facing the facade of the building.
4. Polishing - a stone treatment procedure in which the polished surface is polished using conveyors with powder-coated wheels. Next, the material is processed with circles of felt or special matter. The use of chemical compounds helps to achieve a certain shine for the stone. Its color becomes more saturated, and the pattern is fully revealed. Processed stones are used in the process of finishing the interior of the room, for the construction of countertops, etc.
5. The use of conchoidal treatment helps to achieve the presence of a certain kind of depressions, not exceeding 4 mm. The stone becomes more attractive and acquires a certain sophistication. The material is used in exterior decoration and in the implementation of special design solutions.
6. The use of thermal technology helps to achieve the effect of molten stone. This technology is carried out using a thermo-gas-jet machine. At the same time, the color and texture of the stone are very well manifested, and its surface seems to be slightly melted. This kind of material is used in the process of finishing steps, facade parts of buildings, etc.
7. Creating a rocky texture allows you to simulate rough stone processing, while depressions and protrusions are from 5 to 10 cm. This effect is achieved by chipping certain types of stones. The material allows you to emphasize the significance and importance of the building, it is used in the decoration of facade sections.
Stone cutting - features and types
Stone processing using modern technologies involves their division into two types:
- mechanical;
- mechanical-physical.
In the process of chipping, it is possible to achieve a texture that makes the stone look like a rock.
Stone cutting is the most popular way of processing it. For its implementation, a technology is used that involves sawing disk, rope or strip type.
Disc cutting technology involves the use of disc mechanisms in the cutting process. This technique is very common, it is divided into the following types:
- standard disk;
- diamond disk;
- incisive.
The rope sawing method allows cutting any kind of stones, regardless of their density and structure. There are 3 main ways to perform this cutting method:
- rope using abrasives;
- rope-diamond;
- the use of reinforced washers made of hard alloys.
In the production process of hewn products, the impact cutting method has become widespread. It allows you to achieve the exact texture of the manufactured product and is used in the process of cutting out certain parts, such as steps on the stairs.
Another common method of stone processing is the use of ultrasonic devices and an abrasive medium. Carrying out the process requires a large amount of time, but the processing has the highest accuracy.
Physico-mechanical processing methods involve the use of high-frequency current or a thermoactive gas burner. They are widely used in the process of making monuments from stones that have a particularly high strength.
Cutting stone at home
Considering the degree of complexity of working with stones, they are divided into products with a hard or soft structure. Soft stone is easy to process with a tool that is available at home and is used to work with metal products. For processing hard stones, a special tool is required.
For the processing of stones at home, a special room is required that has an exhaust-type ventilation system. Since in the process of cutting a huge amount of stone dust is released, which is harmful to human health.
Carrying out cutting at home should be accompanied by a constant supply of water, which helps to cool the cutting tool and reduces the release of stone dust.
To perform rough cutting, it is enough to use a grinder with a special nozzle in the form of a disk for stones. For more precise processing, you will need a stone cutting machine with a metal movable platform.
The easiest way to process stone at home is abrasive, that is, cutting the stone with water. It consists in pouring a special powder onto the surface of a plate made of cast iron, which is poured with water. Next, a stone is placed on the surface and friction is performed until the stone acquires the desired shape. Please note that the plate must be made exclusively of cast iron, since it is this material that helps to process stones.
Before cutting, first inspect the stone for defects, try to highlight areas that have a more intense and beautiful pattern. Stones that have other inclusions should not be thrown away; with the right processing, they will look more natural and unique.
To facilitate the process of stone processing, special machines are created, which are based on an electromechanical drive. It appears as an electric motor with an elongated axle, with a power of 0.3 kW. If necessary, a grindstone, circular saw, felt or polishing wheel is attached to the axis surface.
To carry out direct cutting, an additional installation of a bath and a table will be required. For their manufacture, tin is perfect. The bath will collect water, which cools the mechanism during the cutting process. A stone is installed on the box, which will be cut.
On the surface of the bath, you need to install 4 metal corners with holes. The lower corners contribute to fixing the bath on the surface of the bed, and a table with a slot is attached to the upper corners. In order to reduce splashing of water during the cutting process, a special visor should be attached to the table. To make it, you need a tin 1 cm wide and 10 cm long.
To supply water to the bath and the circle, it will be necessary to install a special pipe with a diameter of 0.5 cm and a length of up to 1.5 cm. A rubber hose connected to the water supply is put on it.
At the other end of the pipe, a polyethylene pipe is installed, which slightly touches the circle during operation. Thus, the supply of coolant is carried out directly to the circle.
A steel tube with a diameter of 0.5 cm and a length of 1.5 cm is soldered into the lower part of the bath. Its main function is to drain water and slag, which was formed during the cutting process.
The assembly procedure is as follows:
- the bath is installed on the bed, but is not fixed on it;
- a diamond-type cutting wheel is put on the axis, the diameter of which is about 10 cm, nuts are used to fix it;
- then a table is fixed on the surface of the bath;
- the centering of the circle and the bath in relation to the cutting circle is performed;
- make sure that the circle does not touch the edges of the slot;
- then the bath is fixed with bolts;
- water is connected and the mechanism is tested.
For cutting, hold the stone evenly, gradually bringing it closer to the circle. Note that it is better to mark the cut line with a marker to make an accurate cut. Since with a large allowance, grinding will take a very long time.
For cutting hard stone, a hacksaw is also used, on which a diamond-coated wire is installed. When carrying out this kind of cutting, a constant supply of water will also be required.
Another way to cut stone at home is to saw it. Buy a stone saw - this tool is a modern, modernized device used in construction. In relation to the principle of operation, saws for cutting stone are:
- manual;
- diesel;
- electric.
In relation to the scope of their application, they are divided into:
- jewelry devices;
- building installations;
- industrial machines.
The cheapest and most suitable for home use are hand saws. Their cost is quite low compared to industrial installations, and considerable physical effort will be required to carry out cutting, so with a small amount of work, their purchase becomes quite justified.
A saw with an electric drive has the highest performance. If you need the highest power, it is better to use the gasoline version of the saw.
In addition, saws for cutting stone are stationary and manual. The first option consists of frame, engine, transmission and cutting tool, used in professional stone cutting. Differs in reliability and durability. The hand saw is convenient for everyday use. It is quite mobile and has high maneuverability.
Each of the saws for cutting stone has a special blade, which is based on the use of a metal body with a segmented diamond-coated edge. It is the presence of diamond coating that makes the device more productive and improves the quality of cutting. The speed at which the disk rotates depends on the type and power of the equipment itself. Please note that with an increase in the number of revolutions, the friction between the stone and the blade increases, and accordingly, the saw heats up faster, during the heating process, the quality of the diamond coating decreases, which leads to the need to replace the blade.
Waterjet stone cutting - features and benefits
The waterjet cutting method involves the use of an aqueous solution in which certain abrasives are present for cutting stone. This method involves the supply of a mixture under high pressure. During the cutting process, there is practically no dust emission, as it mixes with water.
This cutting technology is based on the principle of erosion, the natural destruction of stone with the help of water.
Some of the benefits of using this cutting method include:
- high cutting precision;
- the presence of a perfectly even edge of the surface;
- the possibility of artistic cutting of stones;
- complete absence of cracks or chips;
- no need for thermal impact on the stone, which helps to reduce its strength;
- during the cutting process, the amount of waste materials is reduced;
- the ability to cut stones of different thicknesses and fractions;
- full explosion and fire safety of cutting;
- environmental Safety;
- obtaining high quality cuts.
Among the disadvantages of this cutting method are:
- low speed of work;
- high cost of work;
- limited resources of the tools that perform cutting.
Characteristics and advantages of diamond stone cutting
One of the most common and highly effective stone cutting methods is diamond cutting. It makes perfectly straight cuts. Diamond blades can easily cut through the hardest types of stones, in the form of granite.
There are two types of diamond cutting:
- dry;
- wet.
The second method is more acceptable, since the dust formed during the cutting process is washed off with a liquid substance in the form of water. Thus, it does not settle in the air and does not harm a person.
The stone cutting disc performs the function of cutting the material. It has special areas with diamond coating. There are two types of diamond discs. The first involves the application of diamond coating only on the surface of the teeth, and the second - on the entire surface.
The diamond cutting procedure involves the gradual grinding of a stone, due to which it is not able to break or crack.
Among the advantages of using this cutting method, it should be noted:
- speed of work;
- high efficiency of the result;
- accuracy of diamond cutting;
- no damage to the material by chips or cracks;
- low noise performance.
The diamond method of cutting stone has the following disadvantages:
- the impossibility of cutting the enameled surfaces of stones, since cracks form in the process of cutting;
- cutting exclusively in a straight line;
- the need for secondary processing of the cut line.

The main advantages of diamond tools are high strength and long service life. With it, you can easily process and cut natural and artificial materials of increased hardness (for example, granite and concrete). It is available in different types: for example, you can purchase hand tools or a variety of attachments for machine tools.
Varieties and features of use
In Moscow, you can buy several types of diamond tools. The choice depends on what kind of work it will be used for. So, cutting wheels are used mainly for cutting plates. Models for dry and wet work are on sale. Due to the use of a special material for the manufacture of cutting wheels and a carefully thought-out design, they are distinguished by the following advantages:
- energy savings (requires almost half as much energy);
- high speed of work (increases productivity by five times);
- cutting does not require much effort (the load on the tool is reduced, which increases its service life);
- the cost of the finished product is reduced.
The next type of diamond tool for stone processing is crowns. They are used for drilling holes in various hard materials: for each individual material, a different type of crown is selected. They differ from conventional drills in their high strength and durability: the former quickly burn out or become dull during operation, while crowns work properly for a long period of time.
Grinding cutters are used for surface treatment. With their help, the master achieves a perfectly smooth surface of the material, they can be used to remove old coatings. To work on natural and artificial materials, different cutters are used: for example, natural stone is processed with diamond-coated nozzles.
The nozzles listed above are used in combination with power tools. If it is not there, the master can use a hand-held diamond tool, which includes sanding paper, files and other devices. They are much cheaper, yet easy to use and durable.

Products
Despite the emergence of numerous and very affordable materials of artificial origin, natural stone is still one of the most popular materials in interior and exterior decoration, and not only. Spectacular vases and chic monuments, amazing flower beds and stylish tabletops, unforgettable modern statues, elegant jewelry boxes and other works of art - the list of possible applications of natural stone can be continued endlessly.
In the process of manufacturing any product, the stone must be processed. It will be possible to perform high-quality cutting of stone or sawing blocks, grinding and edging plates, carving, engraving or polishing the surface of the product only if there is a really high-quality tool for stone processing.
Artistic processing of stone allows real metamorphoses, when a product of the required shape and texture appears from a shapeless stone block. However, the result of the work will be determined not only by the talent of the master and the characteristics of the source material, but also by how high-quality stone-working tools are used and whether they are selected correctly.
What stone tool do you need?
The processing of natural stone involves the use of a variety of abrasive and diamond tools that have the necessary performance characteristics. To cut stone of any strength, diamond tools (diamond discs) are most often used, and abrasive tools (including diamond-coated ones) are used to grind the surface.
Often it is the diamond tool for stone processing that allows for maximum speed, amazing accuracy and the highest quality of work.

The processing of stones can be safely attributed to the most ancient occupation. Centuries of experience have been accumulated in this matter, many books have been written about this, but they are more intended for professionals. But it is possible to process stone at home, if you have some tools for this.
Equipment for stone processing at home
It must be said right away that although the cutting, processing and finishing of stone is homemade, this does not mean that you can do it in the kitchen or one of the rooms of the house / apartment. For such work, you need to have a separate room, moreover, equipped with good exhaust ventilation, since during the work a large amount of dust will be generated, which is by no means healthy.
So, at home, you can cut, grind, polish, engrave stones. The first two types of work must be carried out exclusively with a continuous supply of water, which cools the tool and removes the slag formed in the process, and also greatly reduces the amount of dust.
Rough cutting of stone can be carried out with an ordinary grinder with a stone disc. If you need more precise cutting, you need to get a sawmill-type machine with a movable metal platform.
Self-grinding of stone can be done using a grinding machine (stationary or manual), or again use a grinder with grinding wheels. The easiest way to grind small stones (up to 20-25 cm in length) is that you pour abrasive powder on a cast-iron plate, fill it with water and rub the stone until it acquires the necessary smoothness of the surface.
Polishing is carried out using such stone processing tools as a polishing wheel and Goi paste.
Since time immemorial, man has tried to conquer stones. The most famous example of conquest is the Egyptian Pyramids. But even today this natural material is one of the most demanded in the construction, jewelry and other industries. After all, products made of semi-precious stone have a special strength and beauty.
To give a pronounced beauty and the necessary form, master masons use a variety of tools. Stone carving is a source of realization of inspiration in the hands of a skilled craftsman.
So what tools does the master need in his work? Next, stone carving, tools and some nuances will be considered in detail.
There are electrical and mechanical tools for stone processing. It all depends on the type of work.
So, for stone carving, tools such as cutters serve as the basis.
With their help, the master carves out the necessary shape, cutting off everything superfluous from the stone. Grinding and polishing machines are also auxiliary tools of a good craftsman.
Splitting is carried out by gradual upsetting of wedges inserted into drilled holes in the body of the stone.
To work with soft rocks of stone or with artificial stone, a tool such as a file is used. The file can be of various shapes, curved or straight, and serves to form small parts in the product.
Today, in addition to manual tools, there is also a modern automatic tool. Automatic stationary or portable machines and machines greatly facilitate the processing, grinding and carving of stone.
Since the stone can be of different hardness, it was not without improvement in the material from which the stonemason's tool is made.
The most effective is considered a tool with a diamond blade. Despite the fact that the cost of a diamond tool is much higher than its simpler counterparts, it is fully justified. After all, a blade based on diamond is much more practical than a blade based on a standard abrasive combination of silicon with mixtures of plastic, marble chips, magnesia, etc. The unique properties of diamond, which is the most durable material, help to quickly and efficiently deal with a stone block of any hardness.

Professional tool - light stone carving
Today, in the arsenal of a bricklayer, electric machines are becoming increasingly popular. Diamond tools for carving and stone processing are successfully used both in industry and at home.
Stone carving will become much easier if you use machines with diamond discs, which should be part of the arsenal of any professional craftsman. So what is it, diamond discs? This is a steel disc, on the surface of which plates of diamond chips and a binder are applied. The technical characteristics of diamond blades depend on the hardness of the granite to be worked with (the thickness of the plates, the composition of the bond and diamond coating). The plates can be welded or pressed into the steel surface of the disc. The bond ensures the integrity of the cutting element and sharpening during operation. The direction of movement while working on the machine is indicated by an arrow on the diamond disc.
There are 2 types of stone carving using diamond discs: "wet" or "dry" carving.
If the circle heats up unevenly, then this leads to its deformation, and it becomes unusable. After all, vibration and overheating have a detrimental effect on the abrasive, and the plates as a result of this are quickly destroyed. Therefore, in this type of work, carving tools contain special cushions to dampen vibrations. "Wet" carving means cooling the disc during operation with cold water.
For "dry" threading, the inserts are divided into segments and created in waves in order to balance the temperature, avoid overheating and disintegration of the inserts.
One of the hardest rocks is granite. For this type, there is a separate direction of abrasive diamond tools.
In addition to natural stone, today's construction market makes extensive use of artificial stone. This creation of human hands is often impossible to distinguish from natural, since the appearance is almost identical to natural. It is possible to distinguish where the natural stone is and where the “fake” is only by weight. Manufacturers of artificial stone are striving in every possible way to lighten the weight and increase the durability of such an analogue of nature.
To work with artificial stone, in general, the same tools are used as when working with natural limestone rocks. Both conventional carbide abrasives and diamond abrasives are used. However, manufacturers of artificial stone recommend having their own specific tool for each type, which is best suited for carving, grinding or polishing stone. Thanks to this, the master can avoid additional waste in the process of work, resulting from the destruction, chips or scratches of the plates.

Engraving tools
In addition to the devices discussed, there are other special devices for engraving. With the help of them, the master can apply a pattern to the plate, giving it the required relief. Such complex work requires the correct selection of working material and the availability of artistic skills from a specialist. Even small and airy engravings made on hard granite will last for many centuries.
Engraver's hand tools include scarpels, which are faceted steel rods with various tips (“tooth” 2–25 mm). With the help of them, an engraving (drawing) is applied to the surface.
Another engraver's tool is a scriber. Scriber differs from scarpels by the presence of a special victorious tip. It is used to mark the stone and draw deep, straight lines.

Stone processing: types of stonemason work
Nature has generously endowed stone rocks with such qualities as stability, strength, variety of patterns and colors. But in the hands of an experienced stone craftsman, this building material, popular at all times, plays with a special color, just as a diamond acquires its cut in the hands of a jeweler.
There are many types of work on the processing and cutting of stone: carving, engraving, splitting, cutting, grinding, polishing.
What are the types of surfaces and how it is processed? How are they achieved with the help of the skillful hands of a master?
Type of processing "molten stone". To achieve the effect of "molten stone", the slab is subjected to heat treatment using a firing machine and a special burner. The heating temperature of the fire during a direct attack reaches 1000 ° C, due to which the soft cover of the stone is destroyed, and a homogeneous structure of granite with a light texture is indicated (imperceptible differences up to 1 mm).
Stone scratches. This type of stone processing gives the original texture and is the most modern way of influencing the stone. With the help of special machines, longitudinal scratches with a depth of 0.5-1.5 mm are applied to the surface of the working plate. The wall, decorated with a special relief pattern, looks homogeneous on the one hand, but at the same time, each individual element has its own characteristic, different pattern.
"Polished Mirror". This is a type of processing when the front side of the stone slab looks like a gloss: smooth and shiny. With this type of processing, the stone plays with many colors and impresses with its unique pattern. To achieve this effect, electric tools equipped with polishing skins are used. The master at work, gradually reducing the graininess of the working sectors, achieves the effect of a smooth and sparkling surface.
Smooth matte surface. The appearance of the surface of the stone slab has a clearly defined pattern. This effect is achieved by the master using the same tool as to achieve a “mirror” surface, however, the polishing stage ends a little earlier, and the chain of graininess of the working sectors is used incomplete when processing the front side. At the same time, there is no that glossy sheen that with the “mirror” method.
Processing "ancient antiquity". This is an original way of processing stone, the effect of aging stone. Literally in a few minutes, the master artificially “overestimates” the age of limestone by several centuries at once. To achieve these goals, a special acid is used, which is applied to the surface of the plate and burns out all the weak and small places of the material, such as lime, spar, chalk, forming random pores of various sizes. After acid treatment, the stone is polished, clearing the excess cortical surface.
The method of processing the coating "under the rock". With this type of stone processing, the surface of the coating is closest to the relief gifted by nature. This effect can only be achieved using a hand tool. Craftsmen during work use sledgehammers, wedges, stone hammers, with the help of which they break a block into several parts (blocks) along the line of internal furrows (uneven chipping with a drop frequency of 30 - 50 mm).
Irregularity "conchoidal". This type of stone processing resembles an ennobled rock. With this method, small differences in the texture of the stone are allowed within 3-5 mm, while maintaining the imitation of the naturalness of the chip. Masters cut off only sharp irregularities, thereby giving the stone an attractive decorative image. The work uses both electric and manual tools for stone processing. First, a block is split, and then, with the help of grinding, the relief of the stone is smoothed.
